Alasdair MacIntyre: Conceptual Relativism, Thomism and Liberalism

Influenced by Thomas Kuhn, Alasdair MacIntyre develops a conceptually relativistic theory of research traditions, aimed at describing the structure of these traditions and finding a principle that makes it possible to resolve the disputes among them. The article discusses this theory and analyzes its compatibility withThomism, a tradition that MacIntyre claims to belong to, and with liberalism, a tradition he emphatically criticizes.
